Exorbitant fare of CNG-run auto-rickshaws

Nowadays CNG-run auto-rickshaw drivers, in most cases, don't agree to go on meter but on contract demanding 4/5 times the normal fare. They even request passengers to be complicit in their wrongful act if challenged by police. This way, the auto-driver is not only robbing the passenger but also compelling him/her to tell lies. When asked about the reason of such unholy act, the common answer from the auto-drivers is: the auto-owners do not accept the amount fixed by the authorities and they have to pay the owners 2/3 times higher than that. So the auto-drivers are helpless and demand high fare from passengers. The poor passengers can neither speak the truth before the traffic personnel nor can they quit travelling by auto-rickshaws for obvious reasons.
The question is how long this hypocrisy and double-standard will continue. Isn't there any acceptable way to implement the relevant law tensuring cooperation of all the parties concerned?
